The core narrative follows Wadanohara repairing magical barriers, uncovering betrayal by the shark character Sal/Syakesan, and resolving a war with the Totsusa Kingdom, culminating in multiple endings driven by loyalty, sacrifice, and romance. The primary romantic arc is the heterosexual relationship between Wadanohara and her familiar Samekichi, who become an official couple and have a son in the true ending; other relationships follow classic fantasy tropes without identity-based framing. No character-creation systems, pronoun options, gender-swapped established figures, or DEI consultancy involvement exist.

Developer statements emphasize fairytale atmosphere, sea-creature designs, and themes of selfish versus altruistic love, with no activist intent or representation mandates. Dark elements like implied sexual assault in bad endings and body horror are plot devices for horror contrast, not social commentary. Reception focuses on music, characters, and story twists rather than political messaging, with controversies limited to content warnings for violence. The 2013 release predates widespread progressive influence in indie games, resulting in virtually no ideological embedding.
